CROSS-TIE FOR RAlLFlOADS.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed March 1?. 1906. Serial No. 306,502.

T0 at whom it may concern.-

Be it known that I, Dawson Hoorss, a resident of the city of Philadelphia, county of Philadelphia, and State of' Pennsylvania, have invented an Improvement in Cross-Ties for Railroads, of which the following is a specification. r

My invention has reference to cross ti-es for railroads; and it consists of certain im rovemen'ts which are fully set forth in the ollowing specification and shown in the accompanying drawings, which form a part thereof.

The object of my invention is to rovide a construction of metallic cross-ties w ieh shall have reat strength and stability and conform c osely to the shape and resiliency of the ordinary wooden cross-tie.

My invention consists of a cross-tie having its body formed of two channel-shaped bdams of different crosssections and one fittin g over or embracing the other to constitute a boxlike structure combined with bolts or other suitable devices for clamping the rails thereto.

My invention also consists in combining the box-like tie with a series of spaoin tubular ieces or studs arranged between t e perallev top and bottom faces of the two channelbeam sections and through which clampingbolts extend to hold the rails in place.

My improvement further embodies the tie of above construction when reinforced with a filling of suitable non-metallic material which may be poured in the plastic condition and allowed to set or harden to give solidity to the tie as a whole. 7

My invention also comprehends details of construction which, together with the features above specified wil be better understood by reference to the drawings, in which 7 7 Figure 1 is a side elevation of my improved cross-tie with part in section and showing the rails attached thereto. Fig. 2 is a cross-section of same on line 2 2. Fig. 3 is a perspective view of the two channel bearns before being forced to other. Fig. 4 is a perpective view of one of t e tubular spacing-studs, and Fig. 5 is a cross-section shownga brace for the rail on a-curve adapted for ns'e'with my improved crosstie.

7 A is the upper beam and is of channel sha e in cross-section, with the flanges B exten ing downward from sides. A portion of the upper surface of the web at each end is bent downward, as at C to close in the ends as clear] shown in Figs. 1 and 3. those on( s C of the web may be left in the position shown in dotted lines in Fig. 3 until after the filling material M has been introduced and subsequent to which it is bent down in 7 .cold condition.

D is the lower channetbeam and has its flanges E extended upward and fitted within the channel-beam A, as shown in Fig. 2. It will thus be noted that the beam D 13 of less width and of less depth than the beam A, though the latter condition is not essential. As the outer walls of the flanges E are vertical and parallel, I prefer to bend inward the flanges or sides 13 of the beam A, so that they fit snugly-a ainst the said outer surfaces of the flanges of the beam i). it is also evident that, if desired, the flanges E and B may be bent so that they interlock on a dovetail principle, though hardly perce tible to the eye, as such construction woulr tend to hold the two parts A and D together during shipment and handling and before the bolts L are einaloyed.

represents tubular spacing-studs and are made oblong in cross-section and provided at each end with a shoulder H and flan e I, the.

latter fitting the oblong apertures in the webs of the channel-beam sections A and D, as shown in Figs. 1 and 2. If desired these flanges I may simply fit the apertures as bushings or may be riveted therein, as indicatod in Fig. 5, in which case they would act as means for holding the sections A and D togather.

J represents the rails, which rest upon the tie, as shown, and may be clamped in place by the clainpinggilates K and bolts L, which latter extend t ough the a ertures in the One oi studs G and are provided wit 1 square or oblong parts on the shanks next to the head to prevent them rotating when turning up the nuts above the clamping-plates K. In place of the articular means shown for clamping the rail; upon the tie any other means my be employed. 7

Braces, such as shown at K, Fig. 5 might be employed when the track is curve to act as a brace to the rails, and these braces may have downwardiy-extending lugs K, filling the oblon apertures of the studs, so as to grevent iossi is shifting under the radial strains v 1, .conie the rails at such (urn-(l fil 'lhis brace liulso acts or the rail-flange. If desired, the clamping-plates K (shown in Fig 1 may have lugs K similar to those of the brace ii.

The metallic cross-tie made in the abovedescribed manner may be used for the railway, or more preferably the s )ace between the sections A D and around t 1e studs G is filled with concrete, cement, glass, slag, sulfur, or combinations'of'these, or filled with any other suitable non-metallic nuiterial to ive solidity to the tie as a whole. In applymg the filling I refer to pour it into the boxlike structure f i om one end before the end plate C is bent down, as shown in Figs. 1 and 3. When filled with a body material as thus stated, the solidity of the tie is much improved, and in consequence thereof it is possible to have the metal in the beams A and D of considerably less thickness than usually found in the standard rolled channelbeams of commerce, which reduction in thickness would reduce the weight of the metal em loyed, and consequently reduce the cost.

y referring to Fig. 2 it will be seen that there is no possibility of water entering,,be tween the side flanges of the two beams because of the fact that the flanges B of the beam A extend over the under beam D; but I do not restrict myself to this arrangement, as the tie structure may be inverted as a whole, if so desired.

While I refer the construction shown, 1 do not limit myself to the details, as ,these may be modified in various ways without departing from the spirit of the invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
